In general, we cannot help with that sort of problem, but are you getting an error message?
Actually I changed my computer and cannot use InDesign in my new computer. What do I need to do to transfer the monthly subscription to my new computer in order to use the application normally? Thank you
Obviously you should have deactivated from the old machine first, but I believe if you sign in using your Adobe ID from the new computer the cloud software should ask if you want to deactivate the other machines that are already activated and switch the activation to your new computer.
